A house in the Palestinian West Bank village of Sinjil was set on fire overnight Thursday, in an apparent “price tag” revenge attack for the Wednesday killing of IDF soldier Eden Atias.

Five residents of the house, all members of the same family, were treated for smoke inhalation in nearby Ramallah, but no other injuries were reported.

It was not immediately clear how the vandals started the blaze, and there were no immediate arrests. A police spokesman said an investigation of the attack was underway.

Hebrew graffiti found nearby read, “Regards from Eden Atias,” indicating that the arson was part of the “price tag” phenomenon, acts of vandalism or violence typically carried out by right-wing activists as revenge for attacks on Israelis or action by the Israeli government against the settler movement.

Such incidents divert security resources, which are better used to fight terrorism, and “undermine the relatively stable security situation in the area,” the IDF said on Thursday morning.

Atias, 18, was stabbed to death Wednesday while sleeping on a public bus at the Afula central bus station.

His 16-year-old assailant Hussein Rawarda, a West Bank Palestinian who did not have a permit to be in Israel, was captured by passengers and turned over to authorities.

Atias was buried in the military cemetery in Nazareth Illit in a funeral ceremony attended by thousands.
